SD 90 Carlworks

The EMD SD90MAC is a 6,000 hp (4,470 kW) diesel-electric locomotive produced by General Motors Electro-Motive Division. It is, with the SD80MAC, one of the largest single-engined locomotives produced by that company, surpassed only by the dual-engined DD series. The SD90MACs feature radial steering trucks with AC traction motors and an isolated safety cab which is mounted on shock absorbers to lessen vibrations in the cab. The SD90MAC has a wide radiator section, nearly the entire width of the locomotive, which along with their size makes them easy to spot.Source: http://en.wikipedia.org/wiki/EMD_SD90MAC
